Application filed July 1,

To aZ-Z whom it may concern:

Be it known that I, lVI-LLIAM L, Isnrnns, a citizen of the United States, and residing at Elizabeth, in. the county of Union and State of New Jersey, have invented certain new and useful Improvements in Friction Wheels, of which the following is' a specification, such as will enable thoseskijlled in the art to which it appertains to make and use the same.

This invention relates to friction wheels and particularly to. wheels of this class used as drive or transmission wheels for motor vehicles, and the objectof the invention is to provide an improved mounting for the friction facing of wheels of this class whereby the life of "such facing may be materially extended by adjusting certain parts of the mounting therefor; a further object being to provide means for holding the friction facing in proper position at all times under slight pressure or tension; a still further object being to provide means for adjusting the movable parts of the mounting without dissecting ordetaching said parts; and with these and other objects in view the invention consists in a wheel of the class and for the purpose specified which is simple in construction, eflicient in use and which is constructed as hereinafter described and claimed.

This invention is an improvement on that described and claimed in a prior application filed by meFebi'uary 25, 1922, Serial No. 539,147, and is fully disclosed in the following specification, of which the accom panying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Fig. 1 is a diagrammatic view of a friction transmission drive showing my improved f-riction wheel in operative position;

Fig. 2 an enlarged side view of a part of the friction wheel with parts of the construction broken away and in section; and,

Fig. 3 a partial section on the line 3-3 of Fig. 2 and on an enlarged scale.

In Fig. 1 of the drawing, I have shown for the purposeof illustrating one form of my improved friction wheel mmethod of using the same, the two friction drive elements of a motor vehicle and in said figure 5 represents the usual drive wheel mounted upon the shaft 6' propelled the engine of the vehicle, and at 7' I have shown my in1- central portion of the rim outwardly, as

1922. Serial No. 572,286.

proved friction wheel slidably 'mounted upon a shaft 8 and keyed thereto by afkey construction 9, the friction wvheel 7 being operated through a suitablelever 10 in the co usual 1'. any desiredmanner. 1 1 Y The. friction wheel 7," or the rimp rtioil' 11 thereof, isfof the crosssection shown in Fig. 3v of the drawing, the outer face 0.1 periphery portion of the rim being provided at one side thereof with a. projecting flange 12 in the form of a comparatively thin plate, andthe. other side port-ion of the rim cut out as shown at 13, fromthe approximate clearly shown in Fig- 3 of the drawing'w An annular ring or platemember 14 of approximately the same form incross section as the projecting flange 12 of therim 11 is adapted to be mounted in connection with the re cessed side of therim, and said ringer plate member is provided centrally thereof with an outwardly and laterallyprojecting part 15 forming a seat for a friction facing ring or member 16, andthe outer face of the part 15, is tapered from left to right as shown at 17 and the inner face of the friction facing 1 ring or member 16 is tapered to sit uponthe part 15, and it will be noted, that. the laterally projecting portion of the part 15 bears upon a rim '11 of the wheel. to reinforce and strengthen said part 15; I

A plurality of bolts .18 are employed for holding the ring or plate member 14:. inconnect-ion with the rim' 11, the heads 19 of said bolts being held against rotation by project ing members 20*on therim 11, as clearly shown in Fig. 2 of the drawing and two nuts. 21 are preferably employed for retaining themember 14 in position.

The transverse dimension of the friction facing ring ormemher 16 is slightly greater than the projecting part 15 but is less, than the distance between'the flange. 12" of the rim 11, and theriyngor'plate member-14 tofQr-m annular spaces 22 between said parts, as clearly shown in Fig. 3 of the drawing, and a plurality of adjustable"arc shapedj'plate members12'3- aread'apted to be mounted in the spaces 22 and adjustable. radially'ofi the wheel 7 insaid spacesl' The arc-shaped plate: members 23 all of approximately the samecionst ruction and i and 27 through the flange 12 of the rim 11 and the ring or plate member 14 for securing the parts together and for firmly holding the arc-shaped plate members 23 in any desired position of adjustment, said bolts passing through the friction facing 16. The heads 30 of the bolts 29 are held against rotation by projecting members 31 and the flange 12 and plate member 14, as clearly shown in Fig. 2 of the drawing.

The bolts 21 which are passed through the elongated apertures 26 of the arc-shaped plates 23 are provided with two gear faces 32 which are located in such position as to operate in connection with the gear teeth 28 in the elongated apertures 26 of the members 23, and by loosening the lock nuts 33 of the bolts 29 and moving the head 30 of said bolt out of engagement with the members 31 and by rotating said bolts in the proper direction, the arc-shaped plate members 23 may be moved inwardly and radially of the wheel 7 whenever it is desired to present a new facing for the friction ring or facing member 16, and this result can be accomplished without dissecting the parts of my improved friction wheel.

It will be understood that by reason of my improved construction fine adjustments of the arc-shaped plate members 23 may be produced, and it will be apparent that the adjustment of one plate member 23 will move the adjacent end portion of another plate member correspondingly by reason of the interlocking connection between said members. and when the plate members are secured in predetermined positions of adjustment by tightening the nuts 33 of the bolts 29, the gear faces 32 of said bolts will aid in retaining the plate members 23 against movement.

Another distinctive feature of'my present invention consists in the tapering of the part 15 of the annular ring or plate member 14 so that as the plate membervl i is moved inwardly, the friction facing ring 16 is forced outwardly and radially of the wheel and is held in such position under tension so that at all times said friction facing may be held against free movement on the wheel, or the I various parts thereof as well as to form a rigid and durable backing for said friction facing. In other words, the thrust is taken up directly through the part 15 and the rim llof the wheel relieving the strain upon thereof may be made, within the scope of,

the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
